The following data was collected by a student performing the determining the specific heat capacity and molar heat capacity of copper portion of the experiment.A 35.52g copper coil is removed from boiling water and is immediately immersed in a calorimeter with a constant of 63.2J/0C. The calorimeter contains 74.61g of water that is initially at 21.420C. The system reaches equilibrium at a temperature of 24.300C. What is the molar heat capacity of the copper?
Platinum has a face-centered cubic crystal structure and a density of 21.5g/cm3. What is the radius of the Platinum atom
to reach equilibrium (at pH 7.00) through titration by adding 14.25 mL of 0.2030 M NaOH to 20 mL of this solution. What is the Molarity of the acid?
If the graph was a curved line what would this mean. and how would the results be affected if a mistake was made and your temperature was in celcius
Why is Pyrex glass wool, rather than typical filter paper, used for the filtration of the hot solution of K+, [Al(H2O)2(OH)4]- , excess OH-?
Consider the titration of 50.0 mL of 0.217 M HN3 (Ka = 2.6 x 10-5) with 0.183 M NaOH. Calculate the pH of the solution after the addition of 29.6 mL of NaOH solution.
derive the irreducible representations for the normal vibrations of XeF4 and determine which are IR active, which are Raman active
If 5.00 mL of HCl require 4.78 mL of 0.9581 M NaOH to just consume the HCl, what is the concentration of the HCl
The lab was a "Two-Base Extraction" A mixture of benzoic acid, 2-naphthol, and naphthalene was extracted with sodium bicarbonate and followed by sodium hydroxide.
A molecule can be polar or nonpolar depending upon the nature of the bonds and the shape of the molecule. For a molecule that has different outer atoms the molecular symmetry will decide the polarity.
What pH will would measure for these solutions immediately? What would be the pH after the solutions equilibrate with the atmosphere
In the reaction 2A -> X + Y, the initial concentrations are all 0.600 M. If the equilibrium constant is 1.20 x 10^6, what are the equilibrium concentrations
A buffer is prepared by dissolving 10.0 g of NaClO and 10.0 g of HClO in enough water to make 0.500 L of solution. What is the pH of this solution
